Intramuscular haemangiomas of the digastric muscle are often misdiagnosed due to their low incidence and non-specific manifestation. Only two out of six previously reported cases were diagnosed correctly before excision. Ultrasound may not reveal their vascularity, and fine-needle aspiration biopsy is unhelpful as it reveals only blood.
A case of intramuscular haemangioma of the posterior belly of the digastric muscle is described. Previously reported cases are reviewed. Investigations used to diagnose the lesions and reasons for their common failure are discussed.
Core-needle biopsy led to the correct histological diagnosis, and magnetic resonance imaging precisely located the lesion within the digastric muscle.
Core-needle biopsy was safely used in the diagnosis of an intramuscular haemangioma. The combination of core-needle biopsy and meticulous review of magnetic resonance imaging enables accurate diagnosis pre-operatively.
由于二腹肌肌内血管瘤发病率低且表现不具特异性，常被误诊。此前报道的6例病例中，仅有2例在切除前得到正确诊断。超声可能无法显示其血管情况，细针穿刺活检也无济于事，因为其仅能抽出血液。
描述了1例二腹肌后腹肌内血管瘤病例。回顾此前报道的病例。讨论了用于诊断这些病变的检查方法及其常见诊断失败的原因。
粗针活检得出了正确的组织学诊断，磁共振成像精确地将病变定位在二腹肌内。
粗针活检被安全地用于诊断肌内血管瘤。粗针活检与对磁共振成像的细致评估相结合能够在术前实现准确诊断。
